Question

我在django中有一个视图

def shoplist(request, shop, subcategory, discount, format=None):
    args = {}
    args.update(csrf(request))
    args['subc'] = ShopSubCategory.objects.get(id = subcategory).category_id
    args['shopfilters'] = Shop.objects.filter(shop_category_id = 'subc')
return render_to_response('shop-catlist.html', args)

此视图从请求（OK）

获取“子类别”

“子”根据子类别获取类别的ID（确定）

在模板中它可以很好地工作，但如果我尝试在“args ['shopfilters'}中使用”subc“，那么它会给出（带有基数10的int（）的无效文字：'sub'）

如何使用'sub'值作为'shopfilters'的过滤键？

    section = models.ForeignKey(ShopSection,  blank=False)
    name = models.CharField('Name', max_length = 100)
    def __unicode__(self):
        return u'%s' % self.name
